HEATER OR COOLER FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 668,876, dated February 26, 1901.

Application filed June 19, 1900. Serial No. 20,911. @lo model.)

To all whom, it may concern:

Be it known that I, GABRIEL JULES LEON HENRY, a citizen ofthe French Republic, and a resident of Quebec, in the Province of Quebec and Dominion of Canada, have invented a new and Improved Heat-er or Cooler for Liquids, of which the following is a full, clear, and exact description.

My invention relates to devices for transmitting heat for the purpose of heating or cooling liquids, and has for its object the provision of a simple and eficientapparatus for continuously heating or cooling a stream of liquid.

The invention will be fully described hereinafter, and the features of novelty pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarcharacters of reference indicate corresponding parts in all the figures.

Figure 1 is a central sectional elevation of the improved heater and cooler on line l 1 of Fig. 2. Fig. 2isaplan ofthe apparatus. Fig. 3 is a plan of the lower part of the apparat-us shown separately; and Fig. 4 is adetail fragni en tary plan of the feed-tube, the heat-trans# mitting cylinder, and the corrugated ring surrounding said cylinder.

The apparatus consists of two parts, which may be and preferably are separable from each other. The lower part or base A consists of a cylindrical pan or tank having at one side an opening A', by which it communioates with the spout B. At the height of the intended water-level is an overow C, and at the bottom is an outlet D. From a point on the cylindrical wall of the tank A which is between the inlet-opening A and the outlet D a partition E extends inward, said partition being curved and placed at a distance from the cylindrical tank-wall, and the inner end of the partition being in contact with the outer portion thereof, as shown at E, so that there is formed in the tank A a central space A2, surrounded by the partition E, and an annularsurrounding channel A3, leading' from the inlet A to the outlet D, as indicated by the arrows in Fig. 3. The upper end of the tank A is flared outward slightly, as shown at A4, to receive the lower end F of the upper receptacle F. This receptacle has an inclined bottom F2, at the lowest point of which is located an outlet or funnel F2, preferably provided with a sieve F4. At the center of the bottom F2 is located a step-bearing G for a vertical shaft H, the upper end of which is journaled in abearing I upon a cross-bar I, the ends of which have slots I2, adapted to engage upright rodsJ, secured to the top of the receptacle F and screw-threaded to receive nuts J. It will be understood that this construction allows the cross-bar I to be swung clear of the rods J, and said cross-bar, with the shaft H and the parts carried thereby, can be removed from the receptacle, so as to enable all the parts to be readily cleaned.

To the shaft H is secured, by means of arms or spiders H', the heat-transmitting cylinder K, made of metal and provided at its lower portion with a conical ring K, flaring downward and outward. Into said ring extends from below the upper end of an annular inclined ring L, which is stationary, its outer edge being secured to the body of the receptacle F. At the lowest point of said ring or channel L is provided a discharge-tube L', preferably having au upright brauch L2 for theinsertion of a thermometer. At its upper end, upon the outside, the cylinder K carries a ring N, flaring upwardly, the lower edge of the ring being corrugated, and thus spaced at intervals from the periphery of the cylinder, so that liquid discharged into the funnel-shaped ring N, as `from the feed-tube O, will be directed Vinward and flow down the outer surface of the cylinder. At the same time the corrugated edge engages the cylinder K, and thus holds the ring N thereon.

To impart a rotary mot-ion to the heat-transmitting cylinder, I secure to the upper bearing I an annular supply-pipe P, having a feed-tube P' and a series of tangentially-terininating discharge-uozzles P2, adapted to direct jets of a liquid against buckets or Valles K2, carried by the cylinder K upon its inner surface. By providing a greater or smaller number of nozzles P2 and by regulating the flow ot' the liquid, as by ordinary cocks or throttle-valves, the speed of the cylinder may be governed,as well as the quantity of the active liquid.

In operation if it be desired to use the ap- IOO paratus as a cooler the channel AS of the tank A, and preferably, also, the centra-l space A2 thereof, are filled with cold water, into which may be thrown a few pieces of ice to keep the temperature constant. The warm or hot liquid to be cooled is fed through the tube 0 and enters the funnel-shaped ring N, to then flow down upon the outer surface of the cylinderv K. At the same time the cooling liquid, which may be cool water from any source or water withdrawn from the channel AS of the tank A through the outlet D by means of a pump, is forced through the feed-tube P into the supply-pipe P and out through the nozzles P2 against the vanes K2, so as to rotate the cylinder K. The cooling liquid thus ilows down the inner surface of the cylinder K while the latter rotates, and as only the thin Wall of the cylinder intervenes between the cooling agent and the liquid to be cooled the heat will be transmitted in a Very thorough and efcient manner. The fact that the liquid passes between the ring N and the cylinder K in a series of channels, owing to the corrugated construction of the lower edge of said ring, causes the liquid to share the rotary motion ofthe cylinder without being projected outwardly. The rotation of the cylinder is advantageous for the reason that it spreads the liquids on the cylinder-surface, so as to secure contact upon a larger area and to reduce the thickness of the liquid films. l thus secure a very complete contact of the liquids with the cylinder, and the result is a very thorough exchange of heat and cooling action. The cooled liquid drops upon the ring or trough L and escapes through the discharge-tube L', its temperature being readily ascertainable by means of a thermometer inserted in the branch L2, while the cooling liquid drips from the cylinder K upon the inclined bottom F2 and passes through the outlet F3 and sieve F4 into the channel A3, in which it travels around the central space A2 and is thus cooled again, so as to be capable of further use as a cooling agent.

It will be obvious that the device may be used with equal eiiciency for heating purposes, the heating liquid being in this case led to the feed-tube P', While the cool liquid to be heated is fed through the tube O. In this case, if it is desired to return the liquid from the channel A3 to the feed-tube P, the use of ice will of course be discarded and either the tank Awill be heated by means of a suitable burner or other device or the liquid will be passed through a heating device, as a steam-ejector, on its way from the outlet D to the feed-tube P'.

The device is simple, easy to keep in repair, owing to the facility for taking it apart,

and exceedingly efcient, inasmuch as the liquid to be treated and the one which imparts heat thereto or absorbs heat therefrom are separated only by a thin partition, so that there occurs a transfer of heat with very little loss.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A heater and cooler for liquids, comprising a rotary cylinder provided at its upper portion with an exterior surrounding ring spaced therefrom and held to rotate therewith, a feed-pipe discharging into said ring, and another feed-pipe arranged to discharge a liquid against the inner surface of the cylinder.

2. A heater or cooler, comprising a tank, a receptacle located above said tank and having an opening leading to the tank, a rotatable cylinder located within the receptacle, buckets or vanes secured to the upper portion of the cylinder on the inside thereof, means for discharging liquid jets against said buckets, and separate means for feeding to the outer surface of the cylinder a liquid of a temperature different from that of the jets discharged against the buckets.

3. A heater or cooler, comprising a tank provided with a partition which extends inward from a point on the wall of the tank and then around within the tank, to form therein a central space and a marginal channel, an inlet and an outlet located in said channel on opposite sides of the partition, a receptacle located above said tank and having au inclined bottom with an opening which leads into the marginal channel of the tank, a rotary open-ended cylinder located within the receptacle and provided at its upper portion with a funnel-shaped external ring, the lower edge of which is undulating and spaced from the cylinder at intervals, a stationary liquidfeed pipe leading to said ring, buckets or vanes located within the cylinder at the upper portion thereof, means for discharging against said Vanes liquid jets of a temperature different from that of the liquid passing through the said feed-pipe, adownwardlydaring ring secured to the lower portion of the cylinder on the outside thereof, and a stationary collecting and discharge channel having its upper edge projected adjacent to said downwardly-flaring ring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
